Bulletin

NOAA AR 2239 produced several C-class flares, but te strongest one came from a region over the eastern limb (C7.4 peaking at 01:34 UT). This flare was related to a partial halo CME which is not expected to reach the Earth. Geomagnetic conditions are quiet. The CME from May 6 may arrive to the Earth tomorrow and cause active geomagnetic conditions.

Today's estimated international sunspot number (ISN): 096, based on 13 stations.
